No Boot Device Available System did not find a device to boot. Off Board Parity Error A parity error occurred on an off-board card. This error is followed by an address. On Board Parity Error A parity error occurred in onboard memory. This error is followed by an address. Parity Error A parity error occurred in onboard memory at an unknown address. NVRAM/CMOS/PASSWOR NVRAM, CMOS, and passwords have been cleared. The system D cleared by Jumper should be powered down and the jumper removed. Pressed CMOS is ignored and NVRAM is cleared. User must enter Setup. BIOS Beep Codes If an unrecoverable hardware problem occurs the computer may emit a number of beeps from the speaker. These are known as beep codes. The pitch and duration of the beep codes may vary but there will always be a set number of beeps. These beeps stem from the BIOS's initial check on the system and will normally occur in the first few seconds of power on. Beeps codes represent a terminal error. If the BIOS detects a terminal error condition, it outputs an error beep code, halts the POST, and attempts to display a port 80h code on a POST card's LED display.
